WE LINK THE VEHICLE UP TO OUR COMPUTERS, THE SOFTWARE IS THEN UPDATED THROUGH BMW GERMANY. THIS USUALLY TAKES ABOUT 1.5 HOURS TO COMPLETE. THE MAPPING IS THEN CHANGED ON YOUR VEHICLES ECU. BMW THEN UPDATES YOUR VEHICLES OPTIONS TO SHOW THAT YOUR VEHICLE IS NOW EQUIPED WITH THE BMW STAGE 1 POWER KIT. SO SOFTWARE UPDATES IN THE FUTURE DO NOT DELETE OR CHANGE THE BMW PERFORMANCE STAGE 1 SOFTWARE ON YOUR EHICLE.
